CVE-2026-10112: Student Management System XSS Vulnerability

CVE-2026-10112 Overview

CVE-2026-10112 is a cross-site scripting (XSS) vulnerability in sambitraj STUDENT-MANAGEMENT-SYSTEM version 1.0. The flaw resides in an unspecified function within the Dashboard Page component. Attackers can manipulate the Name argument to inject malicious script content that executes in the browsers of users viewing the dashboard.

The issue is classified under [CWE-79] (Improper Neutralization of Input During Web Page Generation). An attacker can initiate the attack remotely, but exploitation requires high privileges and user interaction. The exploit details have been publicly disclosed, and the project maintainer has not responded to the issue report at the time of publication.

Critical Impact
Authenticated attackers can inject script content via the Name parameter on the Dashboard Page, leading to session-context script execution against other dashboard users.

Technical Details for CVE-2026-10112

Vulnerability Analysis

The vulnerability is a stored or reflected cross-site scripting flaw in the Dashboard Page of the STUDENT-MANAGEMENT-SYSTEM web application. The application accepts the Name parameter without performing adequate output encoding or input sanitization. When the dashboard renders this attacker-controlled value back to the page, the browser interprets injected HTML and JavaScript as executable content.

Exploitation requires an authenticated session with sufficient privileges to submit the Name value, and a victim must interact with the rendered dashboard for the payload to fire. Successful exploitation enables session-context actions such as DOM manipulation, UI redress, and exfiltration of data visible to the victim within the application. The impact is limited because the vulnerability does not affect confidentiality or availability of the underlying system, only integrity within the user's browser context.

Root Cause

The root cause is missing neutralization of user-supplied input during HTML page generation. The application writes the Name argument into the dashboard response without HTML-encoding metacharacters such as <, >, and ". The flaw maps to [CWE-79] and stems from absent or insufficient context-aware output encoding in the templating layer.

Attack Vector

An authenticated attacker submits a crafted Name value containing script content through the application interface. When a privileged user loads the Dashboard Page, the unsanitized value is reflected into the HTML response and executed by the browser. The attack proceeds over the network and requires user interaction with the dashboard view.

No verified proof-of-concept code is available. See the GitHub Issue Tracker and the VulDB Vulnerability Report for additional technical context.

Detection Methods for CVE-2026-10112

Indicators of Compromise

HTTP request bodies or query parameters containing <script>, onerror=, onload=, or javascript: sequences submitted to dashboard endpoints accepting the Name argument.
Dashboard HTML responses that echo unencoded angle brackets or event-handler attributes inside the Name field rendering.
Browser console errors or unexpected outbound requests originating from the Dashboard Page after a user session loads.

Detection Strategies

Inspect application access logs for POST or GET requests to dashboard handlers where the Name parameter includes HTML or JavaScript metacharacters.
Deploy a web application firewall rule to flag XSS payload patterns submitted to STUDENT-MANAGEMENT-SYSTEM endpoints.
Run automated DAST scans against the Dashboard Page to confirm whether the Name field reflects without encoding.

Monitoring Recommendations

Alert on Content Security Policy (CSP) violation reports referencing inline script execution on dashboard URLs.
Track outbound network connections from authenticated administrator browsers to unrecognized domains shortly after dashboard page loads.
Audit database records storing the Name field for entries containing HTML tags or JavaScript syntax.

How to Mitigate CVE-2026-10112

Immediate Actions Required

Restrict access to the STUDENT-MANAGEMENT-SYSTEM Dashboard Page to trusted users until a patch is available, since the maintainer has not yet responded.
Apply HTML output encoding at the templating layer for any rendering of the Name field and other user-supplied attributes.
Deploy a strict Content Security Policy that disallows inline scripts on dashboard responses to reduce exploit impact.
Review existing stored Name values in the database and remove or sanitize entries containing HTML or script syntax.

Patch Information

No vendor patch is currently available. The project was notified through the GitHub Issue Tracker but has not responded. Monitor the GitHub Project Repository for fix commits and apply them once published.

Workarounds

Place the application behind a web application firewall configured to block common XSS payload patterns targeting the Name parameter.
Enforce a Content Security Policy header such as default-src 'self'; script-src 'self' to block inline script execution.
Add server-side input validation that rejects Name values containing <, >, ", ', or & characters before persistence.

bash

# Example Content Security Policy header to reduce XSS impact
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'none'" always;
